GeneDx believes in responsible testing that is based on established medical guidelines, and we aim to be completely transparent with our pricing so that patients, clinicians, and payers know the cost of the test.

XomeDxSlice Tool

XomeDxSlice is a custom test for health care providers. Upon client request, GeneDx may elect to offer assistance to the ordering provider in selecting an appropriate list of genes for a specific clinical indication or genetic disorder. However, the provider remains solely responsible for the selection of the appropriate genes and ordering of the genetic testing.

Use this XomeDxSlice Tool to create a custom gene list prior to submission of any patient specimen for testing.

Please use HGNC nomenclature. If a gene symbol is not accepted, visit www.genenames.org or www.omim.org for clarification of nomenclature or other issues.

Note that only nuclear genes with a protein product are appropriate for XomeDxSlice. For genes with poor coverage, other testing methods may be better.

After building your gene list, please select from one of the three options under "What do you want to do?" On the next page, gene coverage will be displayed as well as the option to add or remove genes.

You can return to this initial search page by clicking "Return to Slice Builder;" the gene list will be saved for a short period of time as it is being built.

The XomeDxSlice test code 706 (proband only) is for gene lists of 1-150 genes, while the XomeDxSlice Xpanded test code J757 (with proband or trio analysis) is for lists over 150 genes.

Once the gene list is submitted, it will be auto-approved if proband only (test 706) and 1-150 genes. Other gene lists will be approved or denied by the GeneDx clinical staff within 3 business days.

The approved gene list with the average coverage at 10x or higher will be e-mailed to the submitter.

Suggested Custom Slices (see below) can be customized within the Slice Tool or ordered as-is by entering the Suggested Slice ID or Name on a printed requisition form (e.g. 706 XomeDxSlice, Slice ID: CS-Albinism).

Deletion/duplication analysis of up to 20 genes may be ordered separately with Custom ExonArrayDx. To confirm probe coverage in advance, you may contact genedx@genedx.com, attention Array GC team, or call 1-888-729-1206 (Toll-Free) or 1-301-519-2100 and ask to speak to a genetic counselor in the Array Program.
